摘要： A retractable, roller hearth for use in an industrial heat treat furnace is disclosed whereby the alloy rollers are retracted from their load bearing position when the furnace heat treat processes are underway thus maintaining the rated load capacity of the furnace. A plurality of guided rail support posts and guided, sealed lift posts accurately assure straight line vertical motion of the refractory base enabling contact between fibrous rope seals to seal the hearth from the cooler, lower portions of the furnace when the hearth is in a raised position.
